Detailed Description

The utility model provides a conveniently assembled and disassembled diffusing nipple, which is explained and explained in detail below with reference to the attached drawings.

As shown in fig. 1-5, the utility model discloses a diffusing pipe nipple convenient to disassemble and assemble, which comprises a pipe nipple body 1 and a blocking plate 2, wherein the pipe nipple body 1 and the blocking plate 2 are both made of stainless steel materials. Nipple joint body 1 is the tubular structure, and nipple joint body 1's lower extreme fixedly connected with first connecting portion 11, the periphery wall of first connecting portion 11 outwards extends and forms the flange, is equipped with the connecting hole 111 that distributes along circumference on the flange. The upper end of nipple joint body 1 is equipped with second connecting portion 12, and the periphery wall of second connecting portion 12 upwards extends after outwards extending and forms an annular boss that has connecting groove 121, radially is equipped with a plurality of even interval distribution and to the joint post 13 that extends in connecting groove 121 on the middle part periphery wall of annular boss. The outer peripheral wall of the blocking plate 2 is provided with a plurality of clamping lug plates 21 which are evenly distributed at intervals, the blocking plate 2 is in sealing clamping connection in the connecting groove 121 after the clamping lug plates 21 and the clamping columns 13 are matched and rotated (the specific operation process of the sealing clamping connection is that the clamping lug plates 21 are placed in the connecting groove 121 from a gap between every two adjacent clamping columns 13, then the blocking plate 2 is rotated in a screwing mode, the upper end face of each clamping lug plate 21 can be tightly abutted against the lower side face of each clamping column 13, the lower end face of the blocking plate 2 can be tightly abutted against the groove bottom of the connecting groove 121, and therefore the blocking plate 2 can be tightly blocked at an opening at the upper end of the nipple section body 1 to play a blocking role).

In the actual use process, when the depressurization operation is not needed, firstly, the lower end of the short section body 1 is connected with the bleeding stop valve through the connecting hole 111 on the first connecting part 11 at the lower end of the short section body 1 in a bolt connection mode, and then the upper end of the short section body 1 is plugged by the plugging plate 2 in a screwing mode; when the depressurization operation is required, the blocking plate 2 is firstly detached in a screwing mode, and then the relief or bridging air supplement device is also connected with the nipple body 1 in a screwing mode. In the two application scenes, the operation is carried out in a screwing mode, the traditional multi-bolt dismounting and mounting are thoroughly avoided, and the problems of mismatch of bolt holes and high hole aligning difficulty of the bolt holes are effectively avoided in a screwing connection mode; the operation time can be shortened to be within 15 minutes, and 1 person can perform operation, so that the risk control difficulty is reduced compared with the operation of multiple persons; through the prefabricated pipe that diffuses of revolving the union of twisting that matches with nipple joint body 1 upper end, also only need carry a bridging air supplement unit in the face of complicated operation, easily carry and manage.

In order to enhance the sealing effect and stability between the blocking plate 2 and the short section body 1, as shown in fig. 3 and 5, the connecting groove 121 in this embodiment is designed as a circular groove, a sealing groove 122 is provided on the bottom of the circular groove, a sealing ring 123 is provided in the sealing groove 122, and the sealing ring 123 is preferably an O-ring rubber sealing ring. Set up to four with joint post 13, joint otic placode 21 corresponds and sets up to four, through such design, can let closure plate 2 in the atress of a plurality of directions when the shutoff, reinforcing shutoff intensity. Be equipped with on the periphery wall of annular boss along radial even interval distribution mounting hole 124, four joint post 13 interference are installed in mounting hole 124, and the coincidence of the one end of four joint posts 13 and the periphery wall of annular boss, the other end of four joint posts 13 stretch into spread groove 121 in, can conveniently dismantle through such design, can simplify the preparation technology and prepare easily secondly.

In order to facilitate quick assembly and disassembly, as shown in fig. 3, 4 and 5, the length of the clamping column 13 extending into the connecting groove is smaller than the width of the clamping ear plate 21, so that the blocking plate 2 is convenient to place during initial installation, and quick connection is realized. The setting of joint otic placode 21 is at the periphery wall lower extreme of closure plate 2, two supplementary rotation posts 22 of fixedly connected with on the up end of closure plate 2, and two supplementary rotation posts 22 set up along closure plate 2's radial relative, like this when installation closure plate 2, can realize the rotation of first closure plate 2 with the help of two supplementary rotation posts 22, realize quick connection.
